Portable patient lift assembly

Abstract

A portable patient lift assembly (10) for lifting and transporting a patient comprises a base (12), a support frame (18) extending vertically upward to top ends (20) and a lift frame (28) extending outwardly in a cantilevered fashion from a cross beam (26), and interconnecting the top ends (20). The support frame (18) includes a pair of vertical legs (22) and angled leg braces (24) which are spaced at the base (12) but overlap at the cross beam (26). The lift frame (28) includes one pair of braces (34) extending horizontally between the lift frame (28) and the joint at the ends of the cross beam (26) and the legs (22) and the leg braces (24). A second pair of braces (32) braces the lift frame (28) to the leg braces (24).

What is claimed is: 
     
       1. A portable patient lift assembly for lifting and transporting a patient comprising: a base;   a support frame extending vertically upwardly from said base to spaced top ends;   a cross beam interconnecting said top ends;   a lift frame extending outwardly in a cantilevered fashion from said cross beam to a distal end;   said assembly characterized by said lift frame having sides spaced inwardly from said top ends of said support frame, said cross beam having ends, the first pair of braces having upper and lower ends, said upper ends attached to said sides of said lift frame and extending downwardly and outwardly to said lower ends, said lower ends attached to said support frame, below said top ends thereof;and   said lift frame including a second pair of horizontal braces having outer ends and inner ends, said outer ends attached to said sides of said lift frame and spaced inwardly from said upper ends of said first pair of braces, said inner ends attached to said support frame at said top ends thereof.   
     
     
       2. An assembly as set forth in claim 1 wherein said support frame includes a pair of spaced side leg braces having bottom ends spaced outwardly along said base from said support frame. 
     
     
       3. An assembly as set forth in claim 2 wherein said support frame includes a pair of spaced legs extending vertically upwardly from said base to said top ends. 
     
     
       4. A portable patient lift assembly for lifting and transporting a patient comprising: a base;   a support frame extending vertically upwardly from said base to spaced top ends;   a cross beam interconnecting said top ends;   a lift frame extending outwardly in a cantilevered fashion from said cross beam to a distal end;   said assembly characterized by said lift frame having sides spaced inwardly from said top ends of said support frame, said cross beam having ends, a first pair of braces having upper ends and lower ends, said upper ends attached to said sides of said lift frame and extending downwardly and outwardly to said lowerends, said lower ends attached to said support frame below said top ends thereof; and   said support frame including a pair of spaced side leg braces having bottom ends spaced outwardly along said base from said support frame, said support frame including a pair of spaced legs extending vertically upwardly from said base to said top ends, said leg braces being spaced horizontally from said spaced legs at said base and overlap said top ends of said support frame and abut said ends of said cross beam at a joint at said top ends of said support frame.   
     
     
       5. An assembly as set forth in claim 4 wherein said lift frame includes a second pair of horizontal braces having outer ends and inner ends, said outer ends attached to said sides of said lift frame and spaced inwardly from said upper ends of said first pair of braces, said inner ends attached to said support frame at said top ends thereof. 
     
     
       6. An assembly as set forth in claim 4 wherein said inner ends of said second pair of braces abut said top ends of said spaced legs and said leg braces and said cross beam at said joint. 
     
     
       7. An assembly as set forth in claim 6 wherein said lower ends of said first pair of braces abut said leg braces below said joint. 
     
     
       8. An assembly as set forth in claim 7 wherein said base comprises a pair of spaced horizontal beams and a base beam interconnecting said horizontal beams to define an H shape, said horizontal beams having a top and sides. 
     
     
       9. An assembly as set forth in claim 8 wherein said spaced legs extend upwardly from said top of said horizontal beams and said leg braces extend upwardly from the inside of said sides of said horizontal beams. 
     
     
       10. An assembly as set forth in claim 9 including a U-shaped handle disposed at mid-length along said spaced legs, said U-shaped handle having a pair of arms engaging the inside of said spaced legs and extending to ends abutting said leg braces and having sides engaging said spaced legs. 
     
     
       11. An assembly as set forth in claim 10 including a guide bracket attached to said distal end of said lift frame for supporting a hoist. 
     
     
       12. An assembly as set forth in claim 11, wherein a motor drives a belt for lifting or lowering a patient. 
     
     
       13. A portable patient lift assembly for lifting and transporting a patient comprising: a base;   a support frame extending vertically upwardly from said base to spaced top ends;   a cross beam interconnecting said top ends;   a lift frame extending outwardly in a cantilevered fashion from said cross beam to a distal end;   said assembly characterized by said lift frame having sides spaced inwardly from said top ends of said support frame, said cross beam hating ends, a first pair of braces having upper and lower ends, said upper ends attached to said sides of said lift frame and extending downwardly and outwardly to said lower ends, said lower ends attached to said support frame below said top ends thereof, further including a guide bracket attached to said distal end of said lift frame for supporting a hoist said hoist, including a electric motor driving a belt for lifting or lowering a patient; and   said belt extends horizontally from said motor to a position over said bracket and then vertically downwardly past said bracket.   
     
     
       14. An assembly as set forth in claim 13, wherein said belt lifts a patient support bar.
